Abstract: |
A device for omnidirectional image viewing providing pan-and-tilt orientation, rotation, and magnification within a selected field-of-view for use in any application including inspection, monitoring, surveillance, and target acquisition. The imaging device (using optical or infrared images) is based on the effect that the image from a wide angle lens, which produces a circular image of an entire field-of-view, can be mathematically corrected using high speed electronic circuitry. More specifically, an incoming image from any image acquisition source is captured in memory of the device, a transformation is performed for the viewing region of interest and viewing direction, and a corrected image is output as a video image signal for viewing, recording, or analysis. Multiple simultaneous images can be output from a single input image. As a result, this device can accomplish the functions of pan, tilt, rotation, and zoom throughout the selected field-of-view without the need for any mechanical mechanisms to move a camera.

We claim:
1. A device for providing perspective and distortion corrected views of a selected portion of a field of view in a desired format, said device comprising:
- an imaging system for receiving selected optical and infrared images of said selected portion of a field of view and for producing output signals corresponding to said selected optical and infrared images;
- a lens attached to said imaging system for conveyance of said selected optical and infrared images to said imaging system;
- image capture circuitry for receiving and providing digitized signals from said output signals from said imaging system;
- input image memory circuitry for receiving said digitized signals from said image capture circuitry;
- image transform circuitry for processing said digitized signals from said input image memory circuitry according to selected viewing pan, tilt, rotation and magnification degrees and for producing output signals according to a combination of said digitized signals and said selected viewing pan, tilt, rotation and magnification degrees;
- output image memory circuitry for receiving said output signals from said image transform circuitry;
- an input for selected user and external computer input to select said pan, tilt, rotation and magnification degrees, and for converting said selected viewing pan, tilt, rotation and magnification degrees for input to said image transform circuitry to control said processing of said image transform circuitry; and
- an output connected to said output image circuitry for recording said perspective and distortion corrected views according to said selected viewing pan, tilt, rotation and magnification degrees.
